WRS Specifies D registers and I relays to be monitored on a word-by-word

basis

● Function

Specifies the register numbers to be monitored on a word-by-word basis. Note that this

command simply specifies the registers. Actual monitoring is performed by the WRM

command after the register numbers are specified by this command.

When the volume of data is large and you wish to increase the baud rate, it is effective to

use a combination of the WRS and WRM commands rather than just the WRR command.

If the power supply is turned off, the specified register numbers will be erased.

• The number of words to be specified at a time is 1 to 32.

• For the format of response in the event of failure, see subsection 3.1.2.

• The command shown below includes the checksum function.

When performing communication without checksum, do not include the 2-byte

checksum element in the command.
